What Axle Kit to Use?
In this Tech Tip, John responds to a customer request for our thoughts on an axle kit for his project.
“I have a 1947 Plymouth Coupe, and I’d like to know what straight axle kit you would recommend, as well as any additional changes I would need to make for that kit to fit.”
Hi Keith, You inquired about a straight axle kit to use on your ‘47 Plymouth Coupe, and I would assume you are referring to our Gasser style kits. The wheel and tire combo you intend to use can make a difference but for a 56 ½ track width right where the wheels will bolt on kit P/N 9103548 would be a good choice. Based on that, I would also suggest updating your steering box. For the weight of the vehicle a 525 box would be recommended, found on our website under P/N 91032277, and I would also add a new pitman arm P/N 7022940. Drag link length would depend on where you mount the box and the hook up to the column depends on the column shaft size you use. If your box is in good shape it possibly could be used. Shocks and mounts would be up to your preference and the required length.
